How the Red-backed Shrike (\kur{Lanius collurio}) solves the multiple predator conflict?
SYROVÁ, Michaela
I tested the ability of the Red-backed Shrike (Lanius collurio) to solve multiple predator conflict. Nesting shrikes were exposed to two predators presented simultaneously. The Red-backed Shrike is able to solve this conflict by deciding which of the presented predators is the more dangerous and opting for the appropriate defence of its nest.

Which information is included in the alarm call of Red-backed Shrike \kur{(Lanius collurio)}?
MINAŘÍK, Tomáš
The first complex study of the alarm vocalisation of the Red-backed Shrike (Lanius collurio) is presented. Following on from previous studies five stuffed dummies ? Eurasian Sparrowhawk (Accipiter nisus), Common Kestrel (Falco tinnunculus), Eurasian Jay (Garrulus glandarius), European Magpie (Pica pica), and Common Wood Pigeon (Columba palumbus) ? were used to elicit antipredation behaviour. Seven different types of alarm calls are described ? besides the commonly used ?chak?, five mobbing calls and one that possibly warns conspecifics.
